This in the article asynchronous motor is reactive power control to do and manage for from the transformer used. The main element of the current transformer is the measuring instrument, i.e. the sensitive element. Depending on the number of asynchronous motor stator blades, the measurement sensitive element is placed between the main winding and the rotor as a two-ring or three-ring. Measurement accuracy, reliability, and sensitivity increase compared to an independent measuring device. The measuring element loops are independent or connected in series . When the measurement loops are connected in series, the amount of output voltage is doubled. This is explained by the main formulas and schemes that ensure the output of the signal in the form of voltage due to the main and stray magnetic currents generated in the asynchronous motor stator coil. To control the signal in the form of voltage, a method of placing the measuring coil in the form of independence, parallel and series connected loops based on the number of asynchronous motor stator phases has been developed. Taking into account the interaction of various external quantities, the accuracy, reliability and errors of the signal received from the measuring instrument are considered. The static and dynamic characteristics of the current transformer used in the control and management of the reactive power of an asynchronous motor are presented. Due to the difficulties arising in the formation of differential equations describing the transition processes in the primary currents in the secondary signal transformation sections of the asynchronous motor stator coil, signal transmission elements, the research is based on the advanced mathematical apparatus - the graph model and its analytical expressions. To control and control the reactive power of an asynchronous motor, a cumulative and distributed parameter model has been developed, which allows to study the distribution of magnetic quantities and parameters generated in the magnetic pieces of the current transformer with controlled output voltage.
